Smart Garden Pro Kit: Arduino Mega, DHT22, Regression Model - Predict Yield
Build a Multivariate Regression Model to Predict Yield
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your garden into a precision agriculture testbed. This advanced kit deploys an Arduino Mega 2560 sensor network that logs soil moisture, ambient temperature, humidity, and light intensity every hour for four weeks. The resulting time-series CSV becomes the training data for a multivariate regression model you'll code yourself - predicting crop yield from environmental inputs just like agritech startups and research farm trials.
What You'll Build
A self-contained data logger with an OLED live display and microSD archival. Three soil moisture sensors, two DHT22 humidity/temperature nodes, and a BH1750 ambient light sensor feed into the Mega, all timestamped by the DS3231 RTC. After collecting several thousand hourly readings, you'll export the CSV, preprocess the data, and build a regression pipeline in Python to forecast garden yield - complete with a dashboard that shows how each variable influences growth.
What You'll Learn
- Design a multi-sensor data acquisition system on Arduino Mega 2560, wiring over a dozen analog and I2C devices without signal crosstalk.
- Implement reliable hourly logging with DS3231 RTC interrupts and a microSD module, ensuring zero data loss across weeks of autonomous operation.
- Preprocess raw sensor arrays: normalize soil moisture readings, interpolate missing DHT22 humidity points, and apply a moving average to BH1750 light values.
- Build, train, and validate a multivariate regression model in Python (scikit-learn) to predict garden yield from historical environmental data.

Who This Kit Is For
This kit is built for B.Tech ECE/EEE undergraduates preparing their minor or major project, Smart India Hackathon participants working on precision agriculture, and research interns at NITs, VIT, or BITS Pilani who need a reproducible sensor platform for IoT-in-agriculture papers. It's also a perfect CBSE Class 12 informatics practices project - real hardware meets data science in one rigorous build.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion walks you through every connection and code block; if you still need a human, message us on WhatsApp - we'll help you debug the same day.
Does the kit include the regression model code?
The AI companion teaches you to write the Python regression from scratch (with scikit-learn), step by step, using the exact CSV your logger generates. No blind copy-paste - you'll understand every line.
Can I extend the logging period beyond 4 weeks?
Absolutely. The microSD module can store months of hourly data. The companion shows you how to adjust RTC alarms and manage file rollovers for uninterrupted long-term collection.
What if a DHT22 or soil sensor fails during the replacement window?
Report any manufacturing defect within 7 days of delivery, and we'll ship a free replacement immediately - no questions about your soldering or wiring.
Garden - Temperature, humidity, soil, light logged daily for 4 weeks. Regression model predicts yield.
